The Damping Material and Sound Deadener Thread

Dampening:
There are 2 meaning to dampen.

1) To wet something : I unzipped my pants and dampened the grass below with all my strength.
2) To reduce enthusiasm: Watching me pee so much did not dampen her spirits at all!

Damping:

Damping is the technical term for the action of reducing vibrations in any object.
The material used for reducing metallic vibrations in car panels and doors caused when speakers play is called damping.
You get damping sheets (or mats if you will) and liquid (spray or inject or apply on with a brush) damping.

@Sam - Thought so too. Was surprised to find that most car audio sites used the words "dampening" & "sound-deadening".

rocksterraghu · 22nd August 2007, 18:04

So, do you want a damping mat or a dampening mat (Read the first meaning and example very carefully)?

Sam Kapasi · 22nd August 2007, 18:07

Sound deadening is OK.

Dampening is not.

@Shrivz - Thanks for your replies to my pms. Thought I should take this onto the forum, in case someone else is interested.
I found a tyre repair shopowner who showed me the rubber roll you have described. He called it kachha (raw) rubber. One surface was sticky, the other covered with plastic film. I nearly shouted "Eureka". But my joy was shortlived. The shopowner showed me that this sticky surface could only be stuck if folded back on itself. It refused to stick to normal rubber, metal or anything else around.
Did you use this for damping? How on earth did you get it to stick to the door panel - by using Dendrite? Must have been awfully hard work.

shrivz · 24th August 2007, 10:04

@nura: the rubber sheets I used had plastic film (with a scaly texture) on both sides. When peeled off, it reveals the adhesive and can be stuck onto normal rubber, metal et. all.

cheers!

Guys, my rear number plate makes a helluva noise when i turn up the volume anything above 10. Other than this thak thak noise from number plate, there is hardly any noise or vibration.

my question is what material should be used to make the number plate stick to the car body so firmly that if the woofer is blasting it shouldnt budge?

Add a piece of foam behind the number plate to stop vibrations. You don't need damping there.
